This standard operating procedure (SOP) is applicable to the determination of organochlorine pesticides with the possible presence of polychlorinated biphenyls (PCBs) or toxaphene in soil/sediment matrices using a gas chromatograph (GC) with a narrow-bore fused silica column and an electron capture detector (ECD). This SOP is based on Environmental Protection Agency (EPA) Methods SW846/3500B/3540C/3541/8000B/8081A and those requirements set forth in the latest approved version of the National Environmental Laboratory Accreditation Committee (NELAC) Quality Systems section. Gel permeation chromatography [GPC] cleanup is required and is based on EPA/SW-846 Methods 3600C/3640A. Extracts may be subjected to optional cleanup procedures (florisil, tetrabutylammonium [TBA] sulfite or activated copper powder) based on EPA/SW-846 Methods 3600C/3620B/3660B. The compounds of interest and typical reporting limits (RLs) in soil/sediment matrices are found in Table 1, Appendix A.
